After soaking in hydrophilic substances such as various surfactants and polyhydric alcohols or their solutions in polar solvents such as water, methanol, and furopanol, and drying, This is a method for treating cleaning fibers, which comprises spraying a solution of a non-polar oil or fat or a non-polar low-boiling solvent such as these to moisten the fiber and use it for cleaning.

易になった。Recently, dust control products such as chemical cloths, chemical motsupu, and cloaks, which are textiles impregnated with oily substances, have been developed as cleaning tools for homes, offices, stores, pubs, etc., and are effective in removing dust and oily stains. It got easier.

着されて殆んど除去し難いものになっている。However, these oil-based stains generally adhere directly to the textiles of cleaning tools, impregnate them, and penetrate into the fibers, making them difficult to remove even by washing. It is difficult to avoid severe damage. Especially in the case of synthetic fibers and chemical fibers, such as vinyl chloride, nylon, and polyester, which are easily swollen and softened by oils and fats, if oily stains are attached, the fibers will swell and become oily. The dirt seeps into the fibers and becomes dyed, making them almost impossible to remove.

前記の諸問題を解決したものである。The method of the present invention first imparts hydrophilicity to the surface of the fiber, then provides a water-repellent layer of oil or the like on the upper surface, and the oil-based dirt is adsorbed by the water-repellent layer, making it transparent to the left side of Kaii. In addition to preventing seepage into the inside of the fiber,
When cleaning used cleaning tools, the above-mentioned problems are solved by washing the mountain dirt together with the water-repellent layer and removing it, thereby facilitating cleaning and regeneration of the fiber surface.

た後、乾燥させて繊維表面に親水性を付与する。That is, in the method of the present invention, cleaning tool fibers made of natural fibers of animal and plant origin, regenerated fibers, synthetic fibers, or mixtures thereof are treated with hydrophilic inorganic salts, monohydric or polyhydric alcohols, surfactants, etc. The fibers are immersed in a solution of a polar substance or a low boiling point polar solvent such as water or methanol, and then dried to impart hydrophilicity to the fiber surface.

An aqueous oil layer is formed.

Removed and cleaned. Furthermore, the hydrophilic fiber layer has an oil-repellent action that eliminates oily stains and prevents them from penetrating into the interior of the fibers, thereby preventing swelling and dyeing of the fibers.
